摘　　要：为了研究线接触端曲面齿轮副的齿面接触特性,建立了端曲面齿轮副的传动坐标系,推导出齿轮副的瞬时回转轴及瞬轴面.应用齿廓啮合基本定理,从几何学的角度提出了线接触端曲面齿轮副齿面接触算法,求解出齿轮副的齿面接触印痕与齿廓点.根据齿轮副齿面接触分析结果,确定了端曲面齿轮齿面的修形位置.通过齿轮副对滚实验,验证了线接触端曲面齿轮齿面接触算法的正确性.To study contact characteristics of the curve-face gears,a transmission coordinate of curve-face gears was established.The instantaneous rotation axis and the axode of the curve-face gear were derived.The calculation method of meshing point of line contact curve-face gear was obtained based on the fundamental theorem of meshing tooth profile.The tooth contact prints and the tooth profile points were obtained in the viewof geometry.The results of tooth contact analysis of the curve-face gear showthat the positions of profile modification are determined.The calculation method of meshing point of line contact curve-face gear pair was verified via rolling experiments.
